An Introduction to Programming and Proving with Dependent Types in Coq

open access: yesJournal of Formalized Reasoning, 2010
Computer proof assistants vary along many dimensions. Among the mature implementations, the Coq system is distinguished by two key features. First, we have support for programming with dependent types in the tradition of type theory, based on dependent ...

Inductive Logic Programming in Answer Set Programming [PDF]

open access: yes, 2012
In this paper we discuss the design of an Inductive Logic Programming (ILP) system in Answer Set Programming (ASP) and more in general the problem of integrating the two. We show how to formalise the learning problem as an ASP program and provide details on how the optimisation features of modern solvers can be adapted to derive preferred hypotheses.

Tuning the Hydrogen Bond Network Inside the Helmholtz Plane for Industrial Hydrogen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
The hydrogen bond network within the Helmholtz plane, a key component affecting the hydrogen evolution kinetics, remains far from having a consensus owing to the lack of fundamental understanding. Herein, it is discovered that the introduction of the atomic electric field generated by the weak Ru─Ga bonds can further improve the proportion of 4 ...

Self‐supportive Three‐Way Photoelectrochemical System Achieving Uranium Recycling, Organic Oxidation, and Electricity Generation in Complex Waters

open access: yesAdvanced Functional Materials, EarlyView.
A self‐sustaining solar photoelectrochemical cell (SS‐PEC) is developed to recover uranium from aqueous UO22+ with concurrent organic oxidation and electricity production. The monolithical photoanode directly captures electrons from organic compounds, leading to the oxidation of organic compounds and the decomposition of uranium‐organic complexes ...

The importance of key population community engagement and empowerment in HIV programming: insights from a global survey with local implementing partners

open access: yesJournal of Global Health Reports, 2020
# Background Community engagement and empowerment are critical components of HIV programming, especially for key population communities affected by HIV, and are increasingly considered determinants of readiness for a locally financed and managed ...

A Vertically‐Stacked Optoelectronic Sensor for Localized Hemodynamics Monitoring

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a hemodynamics monitoring sensor that features vertically stacked microLEDs and a heterogeneously integrated photodetector. The vertically stacked microLEDs enable localized measurements, and by designing the interoptode distance according to the depth of the target region, this vertically stacked optoelectronic sensor is ...
